UNITED STATES PATENT OFFICE TELESCOPE MOUNT FOR FIREARMS Application February 24, 1937, Serial No. 127,389

7 Claims.

This invention relates to telescope mounts, and more particularly to mounts for supporting telescope sights upon firearms.

One of the objects of the present invention is to provide a simple, reliable and low-cost mount for attaching telescopes to firearms.

Another object is to provide a superior mount whereby telescopes may be conveniently and securely attached to firearms with capacity for adjustment, without, however, permitting any objectionable degree of slackness.

A further object is to provide a superior telescope mount of the type referred to which may be secured to and detached from the firearm structure with a maximum degree of convenience.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art and which are not claimed by me in a separate application.

In the accompanying drawing, in which certain modes of carrying out the present invention are shown for illustrative purposes:

Fig. 1 is a view in side elevation of one form which a telescope mount may assume in accordance with the present invention, and showing the said mount associated with a iirearm-barrel and telescope-tube;

Fig. 2 is a top or plan view thereof;

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1;

Fig. 4 is a similar view taken on the line 4-4 of Fig. 1; and

Fig. 5 is a perspective View of the clasp-member, detached.

'Ihe particular telescope mount herein chosen for the purpose of illustrating the present invention includes a sheetor plate-metal clasp-member, generally designated by the reference character I0, and having a. pair of oppostely-curved base-clasping arms II and I2, integrally united with each other at their upper ends, and also integrally united by means of a tie-web I3 with a pair of oppositely-located tube-clasping arms I4 and I5.

The two complemental base-clasping arms II and I2 are each of substantially semicircular form in cross-section for encircling the top-portion and the side-portions of a telescope-tube 35 in spaced relation thereto. At their lower portions the said arms II and I2 are extended into substantial parallelism, providing coupling-portions I6 and I'I respectively. The extreme lower ends I6 and I'I 55 of the arms are both bent inwardly to respectively provide opposed clasping-fngers I8 and I9 which are spaced apart and extend downwardly and inwardly in converging direction. The inner face of the clasping-iinger I8 engages a similarlysloped portion 20 of a base or support 2I, and in a similar manner, the inner face of the claspingiinger I9 engages a portion 22 of the base 2I, which portion is sloped to conform to the said finger. The base or support 2I is, in the particular instance shown, secured by a suitable number of screws, such as 23, to a barrel 24 or other suitable portion of the firearm structure.

The downwardly-extending coupling portion I6 of the base-clasping arm II is provided with a threaded bore 25 receiving the threaded end of a clamping screw 26, which also extends freely through a perforation 21 in the opposite coupling portion I'I of the base-clasping arm I2, adjacent which the said screw is formed with a knurled and kerfed head 28, the inner face of which latter bears against the outer face of the portion I'I, just referred to.

The clamping-screw 26, just above described, is preferably so positioned that its knurled head 28 is located below the encircling clasping-arm I 2 and the said clamping-screw 26 extends transversely below the telescope-tube 35. A convenient and desirable substantially-symmetrical structural arrangement is thus obtained. In this position the clamping-screw 26 engages with the 20 upper surface of the base 2|, and hence serves to stabilize the clasping-member both against bodily movement toward the barrel 24 and against tilting movement with respect to the block 2 I. It will be noted by reference to Fig. 3 in particular that the inner surfaces of the clasping-ngers I8 and I9, together with the transverse clamping-screw 26, outline (when viewed from the front, rear or in transverse section) what constitutes in effect a dovetailed groove receiving the dovetailed riblike upper portion of the base or support 2|.

Returning now to the tube-clasping arms I4 and I5, it will be noted by reference to Figs. 4 and 5 in particular that the lower end of each depends from an encircling portion thereof and is bent into parallelism with the similar end of the other arm, providing coupling-portions 29 and 30 respectively. The coupling portion 30 of the tube-clasping arm I5 is provided with a threaded bore 3l receiving the threaded outer end of a damping-screw 32 which extends freely through a passage 33 in the coupling portion 29 of the tube-clasping arm I4. The inner face of the slotted head 34 of the clamping-screw 32 bears against the outer face of the portion 29 of the tube-clasping arm I4, as shown in Fig. 4.

Preferably, as is particularly Well shown in Fig. 4, the clamping-screw 32 is similarly positioned below the encircling portion of the clasp-member. It is arranged at the rear of the said clamping-screw 26 and extends transversely of and below the said telescope-tube 35.

The base-clasping arms II and I2 of the claspmember IU are laterally curved, as shown, on an arc substantially concentric with a telescope-tube 35, but their curvature is of such radius as to leave the said tube substantially free of direct restraint thereby. 'Ihe tube-clasping arms I4 and I5 are also laterally curved on an arc concentric with the tube 35, but are proportioned to firmly clasp the exterior surface of the latter substantially throughout their entire length.

When the clasp-member I is in place upo-n the firearm, so that its base-clasping fingers I8 and I9 are firmly clasped upon the portions 20 and 22 of the block 2I by means of the clamping-screw 26, the clasp-member will assume its normal rigid position with respect to the firearm. When now the complemental tube-clasping arms I4 and I5 are firmly engaged with the periphery of the telescope-tube 35, b-y means of the clampingscrew 32, the said tube Will be firmly supported by the clasp-member, but owing to the flexibility of the tie-Web I3, the said tube may be flexed both laterally and vertically with respect to the clasping-arms Il and I2 and the supporting-structure, as indicated by broken lines A in Figs. 1 and 2, so as to permit the said telescope-tube to be initially trued and properly adjusted by any suitable means to compensate for changes in range and wind velocity, or any other purpose. Furthermore, by loosening the clamping-screw 32, the tube-clasping arms I4 and I5 of the clasp-member may be sufficiently freed from the tube to permit the latter to be adjusted along its own axis.

Should it be desired to remove the clasp-member from the base or support, such, for instance, as the block-like member 2|, this may be effected by loosening the clamping-screw 26 to permit the support-clasping arms II and I2 to spring laterally away from the support 2|.

The invention may be carried out in other specic ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
